CONTROLLING DEVICE FOR GARBURETORS.

Specification of Letters Patent. Patented Aug, 15, 1922.

Application filed March 6, 1922. Serial No. 541,403.

To all whom it may concern:

Be it known that we, SAMUEL Claims and ERNESTO LoBo, citizens of the United Mexican States, residing at Mexico city, Federal District, Mexico, have invented certain new and useful Improvements in Controlling Devices for Carburetors, of which the following is a specification.

This invention relates to an adjustable control of the opening movement of the valve stem in carburetors for motors and especially for automobiles.

The object of the invention is to facilitate a cheap device which may be readily and rapidly applied to the carburetor of automobiles, and by means of an adjustable stop pin limit the opening of the valve and thereby limit the amount of gas fed to the motor.

By the use of this device, once the control is set and sealed for a certain velocity, the motor can not be driven at any higher speed without breaking the seal.

Fig. 1 is a perspective view of the controlling device..

Fig.2 is a top view of same, applied on a Ford carburetor shown in dotted lines.

Fig. 3 is a front view of the'controlling apparatus.

The apparatus is made of sheet metal forming a standard havin two legs (1) each providedwith a hole 2). The upper edge of the standard is perforated and angularly. folded so as to form an upper flange (3), while from the middle of the standard is cut out a perforated lower flange (4), also angularly folded so as to leave a horizontal groove or aperture (5).

In Fig. 2 the standard is mounted against the flange cou ling (6) of the carburetor (7) making use 0 the bolts (8) in order to fasten the legs (1) said bolts passing through holes (2). The connecting rod (9) leading up to the driver and which engages in the eye of the valve stem (10) is of course disconnected before applying the standard, so that the stem (10) may extend through said standard and slide in groove (5).

In Fig. 1 a stop pin (11) is inserted into the aligned second holes of both flanges (3) and (4) and a lead seal (12) may be attached to the pin. In such position the motor is allowed to operate at second speed, because the valve stem (10) is retained by the stop pin (11) in a position, which allows but a partial admission of gas to the carburetor.

Though we have shown and described a particular construction which applies to Ford carburetors, slight modifications would adapt the device to any carburetor.

Having thus described our invention what we claim is:

l. A controlling device for carburetors, comprising a standard provided with two legs adapted to be attached straddling over the carburetor, the upper part of said standard being cut out to form a guiding groove for a. valve stem to slide in, a projecting flange at both the upper and the lower edge of said guiding groove and provided with aligned adjusting perforations, and a sealed stop pin piercing said flanges.

2. A controlling device for carburetors, comprising a standard having two legs adapted to be attached to a carburetor; a member connecting said legs and provided with a slot, said slot being adapted to receive a valve stem; and means for adjusting the travel of said stem.

3. A controlling device for carburetors, comprising a standard provided with a slot for the reception of a valve stem; a pair of legs on said standard for attachment to a carburetor; flanges on said standard; and means on said flanges including a pin for limiting and adjusting the travel vof the stem.

In testimony whereof we have aflixed our signatures.
